The Mystery Method: The Foolproof Way to Get Any Woman You Want into BedErik von Markovik and Chris Odom . St. Martin's , $19.95 (288p) ISBN 978-0-312-36011-5

Never at risk of being called humble, Mystery (aka Erik von Markovik), heralded as one of the best pick-up artists in the country, has created a science of seduction. His meticulously researched system, the "Mystery Method," offers advice to men of every ilk, along with complex charts, social science jargon (e.g., Dynamic Social Homostasis and DHV—Demonstrations of Higher Value) and potty humor Mystery comes off as forceful, provocative and excessively arrogant, but one thing is clear: he's good at what he does. You'll laugh, you'll scoff, but in the end, you'll probably learn something. (Feb.)
